A Short Note Of HDMI To DVI Cable

HDTV is the latest in the technological innovations within the television space. The earlier break through was the LCD and other digital displays. With each kind of display the technology needed to support it changed. While LCD used the DVI or digital video interface technology the modern HDTVs use the High definition multimedia interface or HDMI technology. With products of both technology available in the market today, the ability to interconnect them is invaluable and this is just where HDMI to DVI cable becomes so important.

Before we look at how does this cable help us, let us first look at the technologies themselves. They have some similarity that really makes them work so well together and we can use this cable for the same.

The DVI was one of the first digital video standards to be developed. The difference between digital video signal and analog signal is the manner in which information is transmitted. The traditional VGA used analog video signals to bend electron rays and display picture. The modern DVI system uses digital bits to illuminate pixels on the LCD screen and display pictures.

One point about DVI that needs to be noted and is important in understanding the HDMI to DVI cable is that it was designed to carry just video signals. It did not have any provision for audio signals. So for example you have a DVD player with a DVI interface and an audio interface, you would need to connect both to the LCD screen to view the movie and listen to the sounds.

HDMI or High Definition Multimedia Interface was a big improvement over DVI. To start with it improved the quality of picture being displayed by increasing the pixel count per frame. This meant that you would get high definition picture on the screen.Secondly, it was no more a video interface but a multimedia interface. This meant that the signal was a composite audio video signal. This allowed a lot of flexibility in the kind of sources that could use this cable to transmit information.

Today everything from HDTV digital receiver, to gaming consoles support HDMI technology to deliver a great viewing experience. HDMI is compatible with DVI which makes it really good for transitioning the technology. With the HDMI to DVI cable, you can now send video signals to and from DVI sources to a HDTV without any problem.

However, there is one inherent limitation that we need to honour in this setup. DVI signals cannot carry audio signal. This means that even if you use this HDMI to DVI cable you can only get eh video signal. You would need a separate connection for the audio. When you compare this limitation with incompatible screen and source interfaces you would have to agree that this is a great bargain.
